Original CISCO SG250-08-K9-CN 8-Port Gigabit Smart Switch
Item No.: SG250-08-K9-CN
The most intuitive change of sg250-08 is the interface layout. The RJ45 network interface is changed from the back-end incoming line of router to the front-end panel incoming line
Description
Original CISCO SG250-08-K9-CN 8-Port Gigabit Smart Switch Layer 3 Network Switch
Product Overview
SG250-08 supports 802.3ad port aggregation function, which can be used to solve the bandwidth bottleneck of network storage side when multiple users access files at the same time. After the network storage and switch are set, the link status in the lag setting table will be displayed and enabled. At this time, the data bandwidth of NAS will reach 235mb / s by using two terminals to read data in NAS
Product Highlights
● G250-08 supports 802.3ad port aggregation function, which can be used to solve the bandwidth bottleneck of network storage side when multiple users access files at the same time. After the network storage and switch are set up, the link status in the lag Settings table will be displayed as enabled
● SG250-08 is also unambiguous in this respect. The single port transmission speed is stable above 100MB / s whether receiving or sending, and the transmission curve is also very straight
● The sg250-08 has only 8 network interfaces, and the network speed of 2 hosts and 3 ports overlaps, occupying 6 network interfaces in total. The actual transmission speed is stable at 337MB / s, and basically every port is running at full Gigabit speed
Product Application
The firmware system of Cisco's intelligent switch looks more complex, which is divided into two groups: active and inactive. It can be understood as the dual BIOS design of the motherboard. The user oriented active firmware can be upgraded by itself; the inactive firmware is solidified in the memory chip. When the active firmware is damaged, it will switch automatically to prevent the switch from "brick"
The language pack of the web configuration interface can also be upgraded separately. The factory machine only provides the English interface. Users can download the corresponding language pack from the official website according to their needs and then swipe it into the machine. Here, we need to remind Cisco that the language pack update speed is slower than the firmware update, so it often occurs that the new firmware uses the old version of the language pack
Compared with the upgrade of hardware, the change of web configuration interface is more specific. The configuration of 250 series router is divided into three independent interfaces: switch configuration, network management and findit network probe. Users can select the required interface in the login interface.
